Question

The North pole of the Earth's magnetic field is at the geographical South pole. A compass is a small magnet whose North pole end is drawn in the approximate direction of

• A. the geographical South pole along the lines of the magnetic field
• B. the geographical North pole along the lines of the magnetic field
• C. the geographical South pole against the lines of the magnetic field
• D. the geographical North pole against the lines of the magnetic field

Hint:

The Earth's magnetic field is aligned in such a way that the North pole of a compass magnet points towards the geographic South pole, which is the magnetic North pole.

Answer 1

The Correct Option is B

The Earth's magnetic field has a North-South polarity.
By convention, the North pole of a magnet is attracted to the South pole of the Earth's magnetic field, and vice versa.
Since the North pole of a compass magnet points towards the geographical South pole (the Earth's magnetic North pole), the North pole of the compass aligns with the magnetic field lines towards the geographic North pole, which is along the lines of the magnetic field.

Thus, the correct answer is (b).
